Hello,

I’m trying to make a movieclip (contentMain) scroll on the y-axis (using mouse wheel, not pan) with the following code:

mouseListener = new Object();  
mouseListener.onMouseWheel = function (delta) {  
contentMain.\_y += (delta\*4);  
}  
Mouse.addListener(mouseListener);

The problem is this simple code makes a movieclip scroll vertically but out of the masked area.  
I don’t know how to give the movieclip an upper/lower scroll limit.  
Could anyone give me hand?
